本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图1-7，通过具体的实施例及其应用场景对本申请实施例提供的一种电子设备进行详细地说明。
如图1所示，该显示组件可以包括显示屏10、金属导电层20和绝缘保护层30。
具体地，显示屏10、金属导电层20和绝缘保护层30依次叠设；绝缘保护层30包括至少一个过孔301，绝缘保护层30背离金属导电层20的一侧设置有至少一个形变件40，形变件40通过过孔301与金属导电层20电连接； 在显示屏受力的情况下，形变件40变形并输出电信号至金属导电层20。
其中，形变件40可以是电阻，也可以是压电陶瓷等，形变件40的数量可以是一个、两个或更多个，本申请实施例中不做具体限定，当形变件40的数量为多个时，其分布位置不作限定，以实际情况为准。
可选地，显示屏10的显示侧具有目标区域，目标区域受到压力时可以使压感模组产生形变，目标区域的数量可以为一个，也可以为两个或更多个，本申请实施例中不做具体限定，根据实际情况确定。
其中，金属导电层20可以是设置在显示屏10上的涂层，也可以是粘贴在显示屏10上等。绝缘保护层30也可以是设置在金属导电层20背离显示屏10一侧的涂层，也可以是通过粘贴设置在金属导电层20上。过孔301中可以填充有导电材料，例如金属材料、石墨材料等，过孔301的数量和位置可以根据形变件40的数量和位置确定，具体地，过孔301的数量可以等于或与形变件40的数量。
值得说明的是，本申请实施例提供的显示组件除上述部件外，还可以包括偏光层、玻璃基板层、滤光层、偏光层、发光层等，本申请实施例中不做详细说明，不同的显示组件可以包括不同的结构。
在本申请实施例中，显示组件可以包括显示屏10、金属导电层20和绝缘保护层30，其中，显示屏10、金属导电层20和绝缘保护层30依次叠设，绝缘保护层30包括至少一个过孔301，绝缘保护层30背离金属导电层20的一侧设置有至少一个形变件40，形变件40通过过孔301与金属导电层20电连接，在显示屏10受力的情况下，形变件40变形并输出电信号至金属导电层20。本申请实施例可以通过设置于显示屏10背离显示面的一侧的金属导电层20、绝缘保护层30以及形变件40组成屏下压感模组，形变件40的形变会产生相应的表征压力的电信号。可选地，形变件40的形变量越大，输出的电信号越大，反映出显示屏受到的压力越大。由于显示屏10的面积较大，可以实现的控制模式更多，进而可以为用户提供更加丰富的人机交互需求， 提升用户体验。将压感模组与显示屏10相结合，可以使得整体的厚度减小，进而减小电子设备的厚度，进一步提升用户体验。
如图2所示，在本申请的一个可能的实施方式中，显示屏10可以包括显示层111和绝缘基板层112。
具体地，绝缘基板层112设置于金属导电层20背离绝缘保护层30的一侧，显示层111设置于绝缘基板层112背离金属导电层20的一侧。
也就是，金属导电层20、绝缘保护层30以及形变件40可以组成压感模组，并且通过显示屏10中的绝缘基板层112将上述压感模组与显示屏10的显示层111绝缘，实现压感模组与显示层111相结合，形成屏下压感模组，可以实现多种压感控制，满足用户的多种需求。
如图3所示，在本申请的一个可能的实施方式中，显示组件为有机发光二极管组件(Organic Light-Emitting Diode，OLED)。
相应地，显示屏10包括显示层121，金属导电层20为有机发光二极管组件的铟锡金属氧化物(Indium Tin Oxides，ITO)走线层，绝缘保护层30为有机发光二极管组件的绝缘基板层311，在显示屏受力的情况下，形变件40变形并输出压力信号至ITO走线层211。
也就是，在显示组件为OLED屏的情况下，可以利用OLED屏中的ITO走线层211代替压感模组中的金属导电层20，利用OLED屏中的绝缘基板层311代替压感模组中的绝缘保护层30。
在本申请实施例中，可以通过OLED屏中结构代替上述实施例中的压感模组中的金属导电层20和绝缘保护层30，可以进一步减小压感模组的厚度，使得用户体验更佳。
如图4所示，在本申请的一个可能的实施方式中，显示组件为液晶显示组件(Liquid Crystal Display，LCD)。
相应的，显示屏10包括显示层131、金属接地层132和绝缘基板层133。其中，绝缘基板层133设置于金属导电层20背离绝缘保护层30的一侧，金 属接地层132设置于绝缘基板层133背离金属导电层20的一侧，显示层131设置于金属接地层132背离绝缘基板层133的一侧。
也就是，在显示组件为LCD屏的情况下，可以利用LCD屏中的绝缘基板层133将LCD屏中的金属接地层132，也即In-cell屏的金属壳，与压感模组中的金属导电层20绝缘，实现压感模组与显示层相结合，在In-cell屏上形成屏下压感模组，可以实现多种压感控制，满足用户的多种需求，同时也可以减小压感模组的厚度。
其中，LCD屏除了上述结构外，还可以包括背光灯，导光膜，偏振片，液晶层等结构。具体地，当显示组件为In-cell屏时，一般在导光膜的背离显示面的一侧还有一层金属壳作为触屏等的参考地，即In-cell屏的金属壳。
进一步地，如图5所示，绝缘基板层上可以设置有至少一个接地过孔1331，金属导电层20通过接地过孔1331与金属接地层132电连接。
也就是，在显示组件为LCD屏的情况下，绝缘基板层133上可以设置接地过孔1331，使得金属接地层132可以作为压感模组的参考地，增强压感模组的抗干扰能力，也可以提升对形变件40微小的变形的灵敏度，使得压感模组的检测灵敏度更高。
其中，接地过孔1331中可以填充导电材料，例如金属材料、石墨材料等，接地过孔1331的数量和位置本申请中不做具体限定，可以根据实际情况确定。
如图8所示，在本申请的一个可能的实施方式中，可以将形变件40设置于绝缘保护层30的过孔301内，形变件40直接与金属导电层20电连接。
具体地，可以将形变件40镀在金属导电层20上。在显示屏受力时，力通过各层传递至形变件，使得形变件发生变形。形变件40的形变会产生相应的表征压力的电信号。由于形变件40位于过孔301内部，可以减小整体在垂直于显示屏的厚度减小，进而减小电子设备的厚度，进一步提升用户体验。
在其他实施例中，过孔可以是金属过孔，形变件40镀在金属过孔的孔壁上。在显示屏受力时，力通过各层传递至绝缘保护层，绝缘保护层形变使得 形变件产生形变，从而产生相应的表征压力的电信号。
在其他实施例中，形变件40也可以通过粘贴设置在金属导电层20上。形变件40在垂直于显示屏10的方向上的长度可以大于绝缘保护层30在垂直于显示层10的方向上的厚度，在显示屏受力时，形变件40位于过孔301之外的部分受到压力，将电信号传递至金属导电层20。形变件40在垂直于显示屏10的方向上的长度也可以小于绝缘保护层30在垂直于显示层10的方向上的厚度，在显示屏受力时，力通过各层传递至形变件，使得形变件发生变形，从而产生相应的表征压力的电信号。
在本申请的一个可能的实施方式中，绝缘保护层30的过孔301中可以填充导电材料，例如金属材料、石墨材料等，过孔301的数量和位置可以根据形变件40的数量和位置确定。
可以通过导电材料使得形变件40与金属导电层20电连接，形变件40全部位于过孔301之外，在显示屏受力时，形变件整体发生变形，并将电信号通过填充材料传递至导电层20，由于形变件整体受力变形，可以使得测量更加准确。
进一步地，在垂直显示屏10的方向上，形变件40的投影至少部分位于过孔301的投影之内。
也就是，形变件40可以通过过孔301中填充的导电材料与金属导电层20电连接，这样使得电连接的信号更加稳定，在显示屏受力时，可以更好的传递至形变件40，使得测量更加准确。
在本申请的一个可能的实施方式中，如图6所示，形变件40的数量可以为四个，相应的过孔301的数量也可以为四个。四个形变件40可以组成惠斯通电桥。
在本申请实施例中，通过多个形变件40可以使得检测的压力值更加准确，可以检测到微小的形变后产生的压力变化。
可选地，形变件40的个数可以为多个，在目标区域受到压力的情况下， 可以在多个形变件40中选择距离压力触发点最近的、形变量最大的四个形变件40组成惠斯通电桥。
目标区域的形变导致每个形变件40也变形，且形变量和方向存在差异，当压力垂直显示屏10自上而下通过金属导电层和过孔传递至形变件40时，不同位置的形变件40由于受力不均匀而产生不同的形变量，进而产生不同的电压变量。电压变量的大小取决于其与压力触发点A的位置远近，越靠近压力触发点，则形变量越大，并且自压力触发点为中心呈近似圆形地自内而外压力值降低。此时可以根据形变件40的形变量转化的电压变化值计算出压力值。
例如，如图6-7所示，图中GND为接地。组成惠斯通电桥的四个形变件40分别为四个电阻R1、R2、R3和R4。惠斯通桥的电压变化如下式所示。可以根据下式计算出电压变化值即输出信号，再经过转换变为压力值。

在本申请的一个可能的实施方式中，金属导电层20可以为设置于显示屏10的镀层。
也就是，金属导电层20可以是镀在显示屏10上的金属层。
可选地，本申请实施例还提供了一种电子设备，包括上述任一实施例提供的显示组件。且可以实现上述显示组件的任一功能，本申请实施例中不做具体限定。
本申请中的电子设备可以是全面屏手机、平板电脑等设备，具体地本申请中不做详细介绍，以实际情况为准。
